Dri-release®:Dri-release® is a patented technology utilizing an intimate engineered blend of moisture absorbing and moisture repelling fibers. The moisture absorbing fibers pull moisture through the fabric while the moisture repelling fibers push the moisture to the surface of the garment where it can evaporate quickly as airflow moves across the fabric.

Stretch Nylon:Continuous nylon filaments that are crimped and heat set to provide elasticity. Due to the relatively high level of elasticity imparted to nylon after it is crimped and heat set, it is very commonly utilized to make stretch socks in combination with other yarns.

Elastic (rubber):A rubber or spandex (synthetic elastic) that provides extreme stretch and recovery. It is usually wrapped with a man-made filament yarn in order to provide consistency in its stretch and recovery.
